I've been reading all the Sound/PulseAudio/ALSA threads over the last couple of days and one of the suggested solutions fixed my problem. This solution is in other threads but in case someone is following this one, I'm repeating it here.

Edit /etc/pulse/default.pa. Find the line:

load-module module-hal-detect

and add tsched=0 on the end, then save and restart PulseAudio.
